Indlela yokwenza unikezelo lwamandla olulawulwayo kunye ngezandla zabo

Ukususela nqaku, uya kufunda indlela yokwenza mindzulamiso umbane ngezandla zakhe kwezi zinto zokufunda ezikhoyo. Ingasetyenziswa ukwenza izixhobo zokusebenza ekhaya igunya, ngokunjalo eemfuno elabhoratri yethu. umthombo wamandla ombane DC zingasetyenziswa ukuvavanya izixhobo ezifana gqatso umlawuli Alternator ngomatshini. Eneneni, xa kuyimfuneko kuba ukuhlola yombane ezimbini - volts 12 ngaphezulu kwe 16 Ngoku, cinga iimpawu ze-supply amandla.

transformer

Ukuba ifowuni ukuba kusetyenziselwa bamthethela umgcini NICD iibhetri kunye nezixhobo aphezulu amandla, akukho mfuneko yokusebenzisa abaguquli ezinkulu. Lwanele ukusebenzisa imodeli, amandla apho kungekho watts ngaphezu kwama-50. Kodwa ke, ukwenza umbane adjustable ngezandla zabo, ukuthatha kancinci ukutshintsha kuyilo lokuguqulela. Into yokuqala ufuna ukufumanisa oko uluhlu utshintsho ombane na isiphumo. Le parameter ixhomekeke iimpawu nesiguquli-supply amandla.

Masithi wakhetha uluhlu 0-20 volts, ngoko ufuna ukwenza uqalo kwi yala maxabiso. Secondary ngokubhijela kufuneka babe ifildi imveliso ombane ka 20-22 volts. Ngenxa yoko, eshiya primary sombane jiko, phezu kwayo aqhube zamabanga jiko. Efunyanwa ukusuka kwishumi ukuya ukubala inani elifunekayo amathuba, isilayidi ombane wekhadi. Enye ngolweshumi eli xabiso, - ombane evela Ikhoyili omnye. Emva kokuba coil zasesekondari, kuyimfuneko ukuvelisa indibano kunye engundoqo coupler luza kwenziwa.

rectifier

Njengoko ibandla rectifier ezinokusetyenziswa kwakunye ilight ngamnye. Phambi kokwenza unikezelo lwamandla olulawulwayo, enze ukhetho kwanangamacandelo alo. Ukuba ngobunzulu yangoku omkhulu imveliso, kuya kufuneka usebenzise semiconductors abanamandla. Kunqweneleka ukuba ukuzifaka phezu radiators aluminium. Kuba uhlelo, kuqala kufuneka anikwe kuphela bhulorho, njengoko sele ukusebenza eliphezulu kakhulu, ilahleko ngaphantsi kwe ombane kwi ukulungisa of alternating current. umntu uyacetyiswa ukuba ukusebenzisa kwisiphaluka nesiqingatha-yomtshangatshangiso, ekubeni kakuhle kakhulu, imveliso kukho ezininzi phamb ukuba bayasigqwetha uphawu kwaye ngumthombo uphazamiseko kwi kunomathotholo.

uzinzo kunye ukulungiswa unit

Kuba eyimveliso somfanekiso kunye komlawuli ombane ilumkile ukusebenzisa i LM317 microassembly. Ngokwezimali kwaye ziyafikeleleka kwifowuni ngamnye evumela ukuba umbandela imizuzu ukuqokelela iyunithi ezikumgangatho ophezulu umbane adjustable ngesandla. Kodwa isicelo yayo kufuna iinkcukacha enye ebalulekileyo - ukuphola kakuhle. Kwaye hayi kuphela ngokohlobo kwiradiyetha kwisixando sokwenziwa. Isibakala sokuba lo ummiselo kunye ombane uzinzo kusenzeka indlela yenkqubo enomdla kakhulu. Izixhobo ishiya kanye ombane apho kuyimfuneko, kodwa igalelo excess igalelo layo senziwa similise bushushu. Ngoko ke, akukho okupholisa microassembly akunakwenzeka iza kuhlala ixesha elide.

Thatha ujongo kwi mzobo, akukho nto onzima. Iyonke ingeniso evela emikhulu emithathu, lo ombane wesithathu isicelo, oko liyasuswa yesibini, kwaye yokuqala ukudibanisa ubonelelo thabatha amandla. Kodwa apha kukho osemqoka encinane - xa zibandakanya phakathi umnatha kunye terminal lokuqala kweelana ibandla, kuba kungenzeka ukuba afeze Ukulungiswa ombane yemveliso. Ngaphezu koko, umbane kulawulwa ngezandla zabo uyakwazi ukutshintsha ombane imveliso njenge kakuhle okanye stepwise. Kodwa uhlobo lokuqala ulungelelwaniso lula ngakumbi, ngoko ke isetyenziswa rhoqo. Kuba ukuphunyezwa oko kuyimfuneko ukuze ibandakanye ukuxhathisa ezahlukeneyo ohms-5. Ngaphezu koko, phakathi ukuphela indibano yokuqala neyesibini kufuneka iseke resistor asisigxina ohms malunga 500.

Icandelo lolawulo olukhoyo kunye ombane

Kakade ke, ukuba usebenzise ifowuni yaba yeyona lula, oko kuyimfuneko ukuze enze ulawulo lweempawu imveliso ayikho - ombane kunye namandla yangoku. Ukwakha isekethe unikezelo lwamandla olulawulwayo ukuze ammeter ifakiwe ethubeni yokukhokela HIV kunye voltmeter - phakathi uthe iimveliso isixhobo. Kodwa omnye umbuzo - I sebenzisa olunjani izixhobo? Le ndlela ilula - ngayo ukufaka ezimbini LED-umboniso, oludityaniswe i-wesekethe yangoku kunye ammeter, kuqokelelwa microcontroller enye.

Kodwa unikezelo lwamandla adjustable, ziveliswe izandla zabo, kunokwenzeka ukuba ezakunyuka iperi multimeters aphansi Chinese. Inzuzo kokutya zabo ivezwe isixhobo ngqo. Ngokuqinisekileyo Ungasebenzisa ucingo izikhombisi, kodwa lo mzekelo oko kuyimfuneko ukuze enze isikali grading for the resistor bume.

iyunithi yokuhlala

izindlu bokwenziwa kakhulu ngentsimbi ezilula kodwa oluqinile. Umgomo engcono ibingaba aluminiyam. Njengoko sele kukhankanyiwe, isiphaluka iqulathe izinto umbane olulawulwayo ukuba shushu. Ngenxa yoko, izindlu mayixhonywe ngaphakathi kwi radiator, nto leyo ibe ngempumelelo enkulu uxhume nge kwenye yeendonga. Kukhethwa ukuba ubukho umoya ngenkani. Ukulungiselela le njongo, ungasebenzisa i iswitshi thermal nesithandwa nge fan. Kufuneka ufake ngqo kwi heatsink.
